I came across a series of products aimed at whimsical spinsters labeled "___ butts drive me nuts," with like, cowboys and corgis and whatnot plugged in. I thought, hey! Demons don't get enough play! So this is the first in a series of delightful demonic duffs. Buttercup starts us off with her classic red devil ass, shiny and freckled and wedgied all to Hell and back.
I've included a PSD at max resolution with no background and transparency intact in case anyone wanted to print off a sticker or decal!
